INSTRUCTIONS 

1. This code book, to be known as the "Colorado" Code, is 
issued to all combatant troops down to battalions. 

It is primarily intended for communication within the divi- 
sion, but may be used for messages to higher headquarters. 

Messages encoded by its use may be transmitted by any 
means at hand, but radio or earth telegraphy should be used 
only when more secret means are not available. 

2. Messages once transmitted in clear or in any other code 
or cipher must not be repeated in this code. 

Messages once transmitted in this code must not be repeated 
in any other code or cipher or in cle;ir. 

Except that number and hour of signature may be in clear 
when preceding first code group, the use of "clear" in code 
messages is prohibited. 

.3. The use of this code for regular routine reports should 
Ik- limited to actual necessities. Such reports should be trans- 
mitted by other means than radio or earth telegraphy. 

4. Avoid use of words not in code book when other words 
with same significance are provided. Words spelled out, letter 
by letter, not only take time to code, transmit and decode, but 
they are one of the favorite points of attack by enemy code 
men. 

5. Where two or more code groups are assigned the same 
letter, syllable, word or phrase, first one and then another 
should be used so that in a series of messages each occurs about 
the same number of times. In particular, no group should ever 
appear twice in the same message. 

6. At least (me group marked "Null" should be used for 
every ten code groups in a message. These should be placed at 
irregular intervals. A "Null" should always occur between 
double letters; thus the word "boot" would be encoded: 

(b) (Null) (o) (t) 

PS J YWX XOG PFV SBY 

.Vote that different groups are used for the letter "0." 

7. Coded and decoded copies of messages must never be filed 
together. All notes and memoranda used in coding or decoding 
messages must always be destroyed, by burning, if practicable. 

8. Messages must be short. Several short messages will be 
less likely to be read by the enemy than one long one. 

Except in emergency, a long message, if it must be sent, will 
be divided into two or more parts and each sent as a complete 
message. 

Very often the best way to handle a long message is to leave 
out unnecessary words. 

9. Addresses will not be used when context of message indi- 



cates for whom intended. When used, thej' must he in code. 

10. Signatures should be sent only when absolutely required. 
When sent, they must he encoded, letter hy letter, if necessary. 
Usually it will he sufficient to indicate origin by some word in 
code book previously agreed upon by each commander and his 
immediate subordinates. 

11. The message handed Signal Corps operator should he in 
the following form, on any suitable paper: 

"No. 1. 15:40 PSJ YWX XOG PFV SBY 

Send this message to First Division. 

J. M. 
1 June, 1918 Capt., 1st Infantry" 

Items should always appear in this order, that is: 

(a) Number of message. 

(b) Hour of signature. 

(c) Body of message. 

(d) Order directing transmission. 

Order directing transmission may also indicate means to be 
tin ployed when deemed necessary by the Commanding Officer, 
but this will, in general, be left to the discretion of the Signal 
Corps. 

Number of mes'sage and hour of signature should be given 
only when they will serve some good purpose. They will be in 
clear. 

Body of message must he entirely in code. 

12. Blank spaces at end of book are for use of divisions for 
designation of organizations and local geographical points, or 
for such other use as may be desired. 

Words assigned will be reported to Corps, Army and General 
Headquarters, and to neighboring divisions.
